Abstract

The post emergence herbicides prometryne (1.0 kg ha-1), diuron (0.3 kg ha-1), MSMA (2.0, 2.4 and 3.0 kg ha-1), 2,4-D (0.25, 0.5 and 1.0 kg ha-1) and 2,4-DB (1.0 kg ha-1) were applied to leucaena (Leucaena
leucocephala cv. Peru) from 1 to 8 weeks after planting. The first three trials contained leucaena plus weeds while the fourth trial contained leucaena only. All herbicides and the remaining weeds suppressed leucaena growth compared to the unweeded control. 2,4-DB and 2,4-D had similar effects on leucaena. Effective weed control will require interrow cultivation and directed post-emergence herbicide spray.
